The title best says it all. After getting leaked earlier by Engadget, the much-anticipated Sony Ericsson PSP Phone might finally be officially unveiled to the public next month, on December 9th to be exact.

PSP Phone launch on December 9

This is, of course, assuming that this isn’t a nasty hoax and the purported invite is legit, and it’s not alluding to some other device apart from the rumored Playstaion phone. Be that as it may, if this is indeed an official invite, we can’t think of any other device that would merit a launch billed as “the most awaited event of the past 10 years.” The use of the Playstation’s signature icons plus a call button certainly helps give us a clue as to what this might be. Unless, this is just meant to throw us off-track which we highly doubt.

Anyway, we’ll know in a couple of weeks time what this mystery device is, and just for the record, if it still isn't clear enough, our money is on the PSP phone.
